AMD Radeon RX 6700S vs NVIDIA GeForce RTX 3090 Ti vs AMD Radeon RX 6850M XT

AMD Radeon RX 6700S

The AMD Radeon RX 6700S is a mobile high-end graphics card for gaming laptops. It uses the Navi 22 chip based on the new RDNA 2 architecture. It uses 1,792 of the 2,560 shaders (= 28 CUs), 112 TMUs, and 64 ROPs. The 128 Bit memory system connects 8 GB GDDR6 with 2 GHz memory clock. Furthermore, the RX6800S includes 32 MB Infinity Cache. AMD specified 1.9 GHz game clock for 7.9 TFLOPS theoretical FP32 performance at a TDP of 80 Watt. This means the GPU is in theory slower than a Radeon RX 6650M (8,85 TFLOPS). The 6700S is the power saving variant of the RX 6700M.

The gaming performance of the RX 6700S should be similar to the Radeon RX 6650M. AMD specifies the performance similar to a low power RTX 3060. When Raytracing effects are activated, it falls behind the GeForce GPUs.

The Navi 22 chip is manufactured at TSMC in the modern 7nm process.

NVIDIA GeForce RTX 3090 Ti

The Nvidia GeForce RTX 3090 Ti is a high-end desktop graphics card based on the Ampere generation. It was announced early 2022 the fastest desktop gaming graphics card.

It uses the big GA102 chip and offers 10,752 shaders and 24 GB GDDR6X graphics memory. The RTX3090ti is rated at 450 Watt.

AMD Radeon RX 6850M XT

The AMD Radeon RX 6850M XT is a mobile high-end graphics card for gaming laptops. It uses the Navi 22 chip based on the new RDNA 2 architecture. It uses all 2,560 shaders (= 40 CUs), 160 TMUs, and 64 ROPs and therefore is similar to the desktop Radeon RX 6700 XT. The 192 Bit memory system connects 12 GB GDDR6 with 18 Gbps memory speed. Furthermore, the RX6850MXT includes 96 MB Infinity Cache. AMD specified 2.463 GHz game clock for 13.3 TFLOPS theoretical performance (SP) at a TDP of 135-165 Watt. The difference to the previous RX 6800M is the slightly increased clock speed of the CPU and GPU.

The gaming performance of the RX 6850M XT should be slightly faster than the old RX 6800M which positioned itself between a RTX 3070 and 3080 for laptops. For 

The Navi 22 chip is manufactured at TSMC in the modern 7nm process.
